Added alphabetical sorting to the lists.
Changed the path accessing the compose-file to be referencing the **actual** compose-file, not just the working dir. That way allowing people to have different naming-schemes for their composes.
- Added a way to choose from a numbered list what to update.
- Repairing some array-mistakes.
- Cleaned up some formatting and presentation.
- Set so that choosing -y or -n with flags wont give a numbered list.
- Edited options, auto-update through either -y or -a (yes or auto) with same result.
Changed the logic in comparing the digests - if the local check had multiple digests for an image, the old logic would be inaccurate.
New logic just check if the newest digest is among the list of local digests, should avoid some false positives.
Added error check so that instead of breaking, if containers cant be checked on the registry (eg. locally built or deprecated) they'll be added to a error-list.
